AS13456 announces 5 IPv4 prefixes covering 4,608 addresses and 0 IPv6 prefixes.

About this network

A city's own address space, one netname across all of it, cut into five overlapping announcements.

What it's used for

• A municipal government's network. 4,608 addresses across five IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• Every prefix is netname NETBLK-SPOKANE-CITY, registered to the city with a second contact called simply Network.
• The five announcements are a /21, two /22s and two /24s, all within 198.1.32.0 upward.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Address space in 198.1 was handed out early, when a city could ask for a block and get one. A municipality holding its own space rather than renting from a carrier is the mark of a network built before that stopped being easy, and kept since because giving it back is not worth the renumbering.
• Splitting contiguous space into five announcements when they all leave through the same two neighbours is usually the residue of separate departments or sites that were connected at different times, each with its own piece, never merged back into one route.
• A contact named Network with no person attached is how a long-lived organisation avoids the record going stale every time somebody changes jobs.
